I have a Sigma EF-500DG Super and I have the same problem with bounce flash on my K20D. Exposure is dead on with straight flash, but it underexposes badly when I use bounce flash. I have the same problem with my K10D, but not as pronounce as it is with the K20D. I thought it was a problem of compatibility with the Sigma unit.
